href="../io/mxCodec-js.html#mxCodec" class=LClass id=link50 onMouseOver="ShowTip(event, 'tt14', 'link50')" onMouseOut="HideTip('tt14')">mxCodec</a> and then transmitted to the server by the <a href="#mxSession.mxSession" class=LFunction id=link51 onMouseOver="ShowTip(event, 'tt8', 'link51')" onMouseOut="HideTip('tt8')">mxSession</a> object.&nbsp; On the server, the XML data is dispatched to each listener on the same diagram (except the sender), and the XML is decoded back into atomic changes on the client side, which are then executed on the model and stored in the command history.</p><p>The <a href="#mxSession.significantRemoteChanges" class=LVariable id=link52 onMouseOver="ShowTip(event, 'tt17', 'link52')" onMouseOut="HideTip('tt17')">mxSession.significantRemoteChanges</a> specifies how these changes are treated with respect to undo: The default value (true) will undo the last change regardless of whether it was a remote or a local change.&nbsp; If the switch is false, then an undo will go back until the last local change, silently undoing all remote changes up to that point.&nbsp; Note that these changes will be added as new remote changes to the history of the other clients.</p><!--START_ND_SUMMARY--><div class=Summary><div class=STitle>Summary</div><div class=SBorder><table border=0
